From e1066a9dbb2b0fed5d0bd28500abd4e0d325385e Mon Sep 17 00:00:00 2001 From: Marcel de Rooy Date: Fri, 4 May 2018 09:34:02 +0200 Subject: [PATCH] Bug 11943: Prevent double accepts in Koha::Virtualshelfshare This 'bug' existed long enough now to finally remove it ;) We do so by deleting the invitation if the borrower already has a share on this list. Actually not that hard. We still need: a unit test and a db revision. Test plan: [1] Share a list. Let user B accept. [2] Without this patch: Share again and let B accept again. [3] Verify that you have two shares for this list in virtualshelfshares. [4] With this patch: Share another list, let B accept. [5] Share this other list again, let B accept again. [6] Verify that virtualshelfshares does not contain double entries now. (Note: This pertains to the second list only.)
